To all-whom it may concern:

Be it known that we, JOHN D. Rrrsou, a resident of Rochester, in the county of Monroe and State of New York, and ERICK G. SAMPSON, a resident of Jamestown, county of Chautauqua, and State of New York, have invented a new and useful Improvement in Looking Devices; and we do hereby declare the following to be a full, clear, and exact description thereof.

Our invention relates to filing cases and has reference more particularly to mechanism for locking the filing drawers or bases so that 'they cannot be opened by an unauthorized person; such asset forth and broadly claimed 1n an application filed by us August 29th, 1907, Serial No. 390,572. a

The present invention relates to certain modifications in the manner of locking and releasing the locking device and comprises the novel features hereinafter set forth and claimed.

In the accompanying drawing Figure l is a front view of a filing case embodying our invention Fig. Bis a horizontal section through a portion of said cabinet; Fig. 3 is a section on the line 3;-3, Fig. 2'; Fig. 4 is a section taken on the line 4--4, Fig. 2; Fig. Sis a rear view of a portion of the filing case; Fig. 6 is an enlarged detail of the locking dog in locking position; Fig. 7 is an enlarged detail of the manner of locking the operating lever;

Fig. 8 is a detail of the operating lever; Fig.

locking strips.

The cabinet 2 may beformed of sheet metal of suitable thickness, and said cabinet is )rovided. with the side walls 3 and rear walls 4. The horizontal )artitions 5 and vertical partitions 6 act to t ividc the cabinet into a series of pockets or pigeon holes 7 for the reception. of the tiling bases 8 which may either be in the form of a drawer or a Ill()(ll licd base haviuga bottom 1) and front 10 provided with suitable means for holding the documents to be filed (not shown).

The locking mechanism shown comprises the frame 11 which is made up of the vertical locking strips 12 and the cross strips 13 secured together by means of the bolts 14. The locking stri )S 12 are formed with slots 15 which are adaptcd to receive the locking dogs 16. These locking dogs 16 have the recesses Specification of Letters Patent.

Application flleti october 26,1907. Serial No. 399,289.

Patented April 28, 1906.

'17 and 18, the recess 18 being made som ciently large to permit the dog to be inserted in said slots 15 so-as to bring the recess 17 into engagement with the said locking strip and when in this position the la 190i said locking do is bent over into t e position shown in ig. 6 so as to secure said locking dog in position and yet permit of its move ment up and down within the slot 15. The dotted line in Fig. 6 indicates the position of the lug 19 before it is bent over to secure the dog in place upon the locking stri f The dog 16 is further provided with the l atch 20 which is adapted to enter the opening 21 formed in the bottom of the'filing base as well as the opening 22 formed in the horizontel partition 5. The outer face of the latch 20 is beveled.,.as at 23, for the purpose folly hereinafter set forth. When said locking dogs 16 are in their lowered position the latch 20 engages the strengthening rod 24 of 7 5 connected to the horizontally movable strap 8 5 or link 27 which is operated by means of the lever 28. This lever 28 is pivoted at 29 to one of the horizontal partitions 5 and hasits 1 outer end projecting out through the casin at the front thereof. This lever 28 is pre 9 0 erably made telescoping so that it can be drawn out to get a long leverage and when: not in use can be pushed inwardly so as not to project. out far beyond the casing. As shown the lever comprises the outer operating bar 30 and the inner substantially tubular section 31 into which said bar slides.

A slot 32 is provided in the bar 30 throu h. which tlui pin 33 projects in order to. ho d said bar from accidental displacement. The tubular- )ortion 31 is provided at its inner end witi a connection 34 connected to the link 27 connecting the toggles. The outer end of the tubular section 31 of the lever is provided with a tongue 35 adapted to be engaged by the latch 37 of any suitable lock 38 mounted on the front of one of the tiling bases to prevent the lever moving in that direction while it is prevented from moving in opposite direction by the casing. In this manner the lever may be locked against movement and when so locked all the filing basesare likewise locked so that they cannot be withdrawn. A rod 39 acts as a guide for the tongue 35 of the lever.

A spring l secured to the plate 26 bears against the stop 41 on the strap 27 and acts to aid in the movement of the toggle.

When our invention is in use and the operating lever is locked in position by the lock 38 none of the filing bases can be withdrawn; If, however, it is desired to withdraw any of the filing bases the lock 38 is released from the lever and the operating ,bar may then'be withdrawn and by swinging said bar in the proper direction the toggle mechanism'will be operated to raise the locking strips 12-and'with them the dogs 16. In th s manner all of the filing bases are released and an one may be removed.

- As t e dogs 16 are permitted a certain amount of movement independent of the vertical movement of the locking strips due to said dogs engaging the slots 15, any one of the filing bases may be inserted when the others are locked by simply pushing the filing base into place, whereupon the inner end of said filing base will come in contact with the bevel face of thelatch 20 and the locking dog will be lifted until the rod 24 has passedsaid latch, whereupon said locking dog will fall and the latch drop into the openings 21 and 22. This dropping of the dog into position prevents the withdrawal of the filing base until the operating lever is a casing, filin bases movably mounted therein, av vertica y movable frame comprislng vertical strips and cross strips connectedthereto,'lockmg devices carried by said vertical strips, toggle mechanism connected to said frame, a lever, connections between said lever and said toggle mechanism and means for locking said lever.

3. In a filing cabinet, the combination of a casing,filin bases movably mounted therein, a vertica 1y movable frame comprising vertical strips and cross stri )s connected thereto, locking devices carried )y said frame engaging said bases, toggle mechanism connected to said frame, a strap connecting said toggle mechanism, a lever connected to said strap, and means for locking said lever.

41 In a filing cabinet, the combination ol a casing, filing bases mounted therein, a vertically movable strip having slots therein, locking devices adapted to engage said slots and havin recesses therein to engage said strip, said locking devices adapted to engage said bases, a lever, connections between said lever and said. movable strip, and means for locking said lever.

5. In a filing cabinet, the combination of a casing, filing bases movably mounted therein, a vertically movable strip having slots therein, toggle mechanism, locking devices in said slots and having recesses adapted to engage said strip, projections on said locking devices adapted to enter openings in said bases, a lever, connections between said lever and said to gle mechanism, and means for locking said ever.

In testimony whereof, we the said JOHN D. RrPsoN and Enron G. SAMPSON have hereunto set our hands.
